Definitions

  • the present invention relates to a lever-mechanism engine, and specifically to a lever-mechanism engine or pump, which, in the following, will be generally referred to as a lever-piston engine.
  • the engine is of a type that has two separately operating pistons.
  • the operation of the engine is based on the thermal expansion or contraction of a medium.
  • the operation may be based on a closed and/or open thermodynamic principle, and in general on exploiting the pressure of a medium.
  • Engines coming within the scope of the invention are, in terms of their operating principle, usually engines and devices based on the expansion of an enclosed medium, such as steam turbines and steam engines, as well as hot-air engines.
  • Engines of this type convert thermal energy into mechanical energy by forcing a gaseous medium to move through a closed thermodynamic cycle. The thermal energy is produced by heating the medium from outside in a boiler or similar heating device.
  • Open-thermodynamic-principle engines in use are of the most conventional type, which generally uses a crankshaft to convert a piston's back and forwards movement to rotary movement, which can be easily exploited as mechanical work.
  • the torque of the crankshaft varies continually and is maximal for only a short period in the working stage, which itself is only a small part of the total operation of the engine.
  • the so-called stroke i.e. the length of the movement of the piston, is greater than the diameter of the piston.
  • the stroke is nearly the same size as the diameter of the piston, but, in these too, the ratio of the effective (piston) surface area to the ineffective (internal surface of the cylinder and its head) surface area is relatively small, thus contributing to the engine's poor efficiency.
  • a so-called rotary-piston engine in which the piston no longer moves backwards and forwards, but produces work by rotating, is also known.
  • the best-known engine of this type is the Wankel engine, which is also famous for the slow progress of its development, due in particular to great difficulties in sealing the piston.
  • the rotary-piston engine has some drawbacks, especially when used as an internal combustion engine, such as the sealing problem already referred to, the difficulty of arranging simple cooling for the engine, and fairly low efficiency.
  • the present invention is intended to help to improve the utilization of energy and create an machine, engine, or pump operating on the lever-mechanism principle, which is efficient, because it can exploit the entire pressure difference of the medium, while also containing few moving parts, the paths of travel of which are short and the sealing of which can be easily arranged, and has friction that is mainly the rolling friction in the bearing, the whole device having a construction that is multi-purpose, simple, and light.
  • An engine according to the invention has a wide torque range, while the effective surface area of the pistons is great in relation to the volume of the cylinder.
  • an engine according to the invention can also be used especially to exploit renewable sources of energy and 'residual' energy that other devices are unable to exploit.
  • An apparatus according to the invention can also be used to exploit relatively low-temperature energy.
  • the engine also does not need external cooling, when using a source of high-temperature energy or 'residual' energy from some other device, being instead able to function as a radiator and/or cooler itself, while simultaneously increasing the overall efficiency.
  • a machine according to the invention When a machine according to the invention is used as an engine, it creates a small pollution load and can even be used to reduce the polluting effect of the exhaust gases of some other engine, as will be described later. These characteristics also extend the use of the engine to certain special applications.
  • An apparatus according to the invention can be used to exploit the pressure of a medium with a good efficiency, as the apparatus can be constructed in a form corresponding to specific requirements.
  • the apparatus when exploiting the power of rapids or tidal power, can be of the same size as the dam structures and can be built for large and/or small amounts of water and pressures.
  • the simplest embodiment of an engine according to the invention includes, to use conventional engine terminology, an engine block, which is shown generally in the figures as a shaded area, without a reference number.
  • the block can be made from any material generally used for this purpose, though, in the typical uses of an engine according to the invention, the same standard of durability is not required as, for example, in a conventional internal combustion engine.
  • the material used can be selected from a wider range than that traditionally available, while, at least in most applications, relatively light materials and those with poor thermal conductivity can also be used.
  • the engine block generally has a flat shape, when viewed along the plane of the paper in Figures 1 - 8. It can be assembled from two or more parts lying on top of each other, which are suitably secured to each other, for example, in the same way as the cylinder head of an internal combustion engine is secured to its cylinder block. However, as stated, there may be several parts, if this will achieve the desired characteristics.
  • the other components in a solution according to the invention naturally comprise gaskets, the piping connected to the various inlet and outlet channels, the valves, heaters, etc. for the medium, and devices used to provide power take-off from the engine.
  • an engine according to the invention includes an engine block (the shaded area), in which, in this case, two cylinders are bored to form working chambers 2 and 3.
  • Shafts 6 and 11 run through these working chambers 2 and 3, at right angles to the surface of the paper in the figures, and are mounted in bearings, with, for example, the ends of the shafts above the paper being set in bearings in the 'head' of the engine, while the shaft ends below the plane of the paper enter the 'base' of the engine and are mounted in bearings in it.
  • the power take-off is from shaft 11, which, for example, has keyways and an eccentric rotary piston 5 attached to it with a key.
  • Rotary piston 5 has rolling bearings, and rings or collars 13 and 14, which reduce friction and seal rotary piston 5 in working chamber 3.
  • rotary piston 5 generally apply, for the sake of clarity, to the combination formed by rotary piston 5 and rolling bearings 13 and 14. If it is necessary, to understand some operation or construction, reference will also be made, in connection with rotary piston 5, for instance, to rolling bearings 13 and 14 and hinge component 15.
  • lever piston 7 The lever device, which, in the following, is referred to as lever piston 7, is attached by bearings to shaft 6 and is, for example, hinged to hinge component 15 in rotary piston 5 between rolling bearings 13 and 14, so that they are in tight contact with each other, without causing significant friction when they move.
  • An alternative possibility is also to equip the lever piston with a spring 10 and, additionally, with bearings 16 to reduce friction and provide a seal.
  • Rotary piston 5 is attached eccentrically to shaft 11 and lever piston 7 is attached to shaft 6, for example, as stated above, but nevertheless eccentrically close to its outer edge, as can be clearly seen in the figure.
  • the large amount of eccentricity is an advantage, because it is precisely the means by which power is created in the lever-mechanism engine.
  • Rotary piston 5 is essentially a cylindrical piece, with a circular cross-section.
  • the outer side of lever piston 7 is particularly shaped as the arc of a circle. Near its end farthest from shaft 6 there is a bore, which is nearly the size of half of rotary piston 5, as shown in the figure.
  • Rotary piston 5 indeed rotates during each cycle into the bore in lever piston 7, when exhaust chamber 4 vanishes almost entirely and empties into open outlet channel 9, which, in the figures, is open to a chamber with a lower pressure.
  • Outlet channel 9 can be led, for instance, to the inlet valve 8 of a second lever-mechanism engine, which may also be only an inlet channel without a valve device, so that there is no limit to the number of engines that can be connected in series in solutions according to the invention.
  • the motor units can be connected to each other, with the rotary pistons 5 of each unit also being connected to each other, by shafts 11, either in the same position or at a desired angle to each other.
  • the volumes of the combined engine units can be varied as desired, to be appropriate to the mediums used, or to suit other requirements and objectives.
  • the engine unit volumes can be varied, for example, by altering the diameter or length of the cylinder or altering the relative sizes of lever piston 7 and rotary piston 5.
  • inlet valve 8 is shown as a diagrammatic solution, because there are many inlet valve systems and devices that suit the engine.
  • Figure 9 shows one such simple solution, in which a cylindrical perforated plate is attached to shaft 11, and closes and opens, as desired, the engine's inlet channel, which may be at inlet valve 8.
  • the engine it is also possible for the engine to have a channel or chamber 17, between the outer jacket and cylinder 1, in the engine block (the shaded area).
  • the shape, size, etc. of channel 17 can vary to suit each requirement, and it may have inlet ports 18 and outlet ports 19 or valves and other devices required in specific cases.
  • the figures and explanations present one solution according the example.
  • the rotary piston 5 of cylinder 1 is in a position, in which lever piston 7 has passed its furthest position from shaft 11 and has already moved closer to it, due to the effect of the pressure of the medium in working chamber 2, because inlet valve 8 is open.
  • the feed and expansion of the medium continue and lever piston 7 pushes rotary piston 5 clockwise, while simultaneously the effect of the medium has also commenced in working chamber 3, where the pressure acts on rotary piston 5, turning it too clockwise.
  • rotary piston 5 presses the medium from the previous working stage in exhaust chamber 4, through outlet channel 9, to a space with an essentially lower pressure.
  • the medium can continue to be fed through inlet valve 8 to working chamber 2, right up to the final stage of the work stroke ( Figure 5).
  • Rotary piston 5 has rolling bearings 13 and 14, which reduce friction and seal rotary piston 5 in working chamber 3.
  • lever piston 7 has bearings 16 and is sprung 10 or equipped with a hinge component 15. This solution will be explained in greater detail (in Figure 9).
  • the efficiency of the lever-mechanism engine can be increased, by using channel 17 to direct possible gases or liquids, which are hotter than the medium and have been created by heating the medium or other combustion, through inlet port 18 and outlet port 19, and between the engine's thermally insulated outer jacket.
  • the medium can continue to be fed through inlet valve 8 to working chamber 2, right up to the end of this work stroke ( Figure 5). Simultaneously, the combustion gases no longer increase the efficiency, as rotary piston 5 has passed outlet port 19.
  • lever piston 7 and rotary piston 5 of cylinder 1 are in working chambers 2 and 3, surrounded by expanded medium while the medium of the previous work stage has been reduced in exhaust chamber 4 through outlet channel 9 to such an extent that rotary piston 5 has rotated in the bore in lever piston 7 and filled the bore entirely.
  • Rotary piston 5 has begun to rotate out of the bore of lever piston 7 while, inside cylinder 1, exhaust chamber 4 is fully open through outlet channel 9.
  • Rotary piston 5 continues to rotate out of the bore in lever piston 7 while exhaust chamber 4 is fully open through outlet channel 9.
  • an operating power solution is for the hot exhaust gases of a conventional internal combustion engine to be led through channel 17 to heat the desired area of cylinder 1 of the engine.
  • the medium creating expansion is usually water/steam, which can also be cooled or condensed, if required, in a series of several engine units according to the invention.
  • Any method or manner at all, that creates a medium of a suitable temperature for each purpose, can be used to create the hot gas or medium.
  • An engine according to the invention can be used, for example, so that the outside of the walls of cylinder 1 are heated by solar heat, for instance, by using mirrors and/or lenses to direct solar heat as a suitably concentrated beam of light to the desired point on the side of the engine, or by using a medium through channel 17.
  • an engine according to the invention could operate, for instance, by heating it with a flame on the outside of cylinder 1.
  • the hot gases created from the combustion of the flame can also be recovered, by sucking them into the engine through inlet valve 8 and, when inlet valve 8 closes, passing the medium, through a separate valve, into working chamber 2 to expand.
  • Figure 9 shows the engine blocks 20 and 40, lever pistons 7 and 27, rotary pistons 5 and 25, rolling bearings 13,14, 33, and 34 and hinge components 15 and 35 between them, in a cross-section through the centre of shaft 11, but with shaft 11 not sectioned.
  • the cross-sections are vertical sections of Figures 1 and 5.
  • lever piston 7 to hinge component 15 in the first engine unit is shown in partial cross-section.
  • the explanation of the operation also uses the reference numbers from Figures 1, 3, and 5.
  • the figure shows two lever-mechanism engine units on the same shaft 11, with their rotary pistons 5 and 25 at 180 degrees to each other.
  • the first engine unit is in ( Figure 1) the starting work and exhaust stroke and the other is in ( Figure 5) the work and exhaust stroke.
  • the medium enters the engine units through a common channel 41, from which valve plate 12 directs the medium to each engine unit, as shown in the figure with an arrow for clarity.
  • Channels 17 are linked in each engine unit, so that the same medium circulates in them from inlet port 18 to outlet port 19, but, as stated elsewhere, there are several alternative solutions.
  • Rotary piston 5 of cylinder 1 is in a position, in which lever piston 7 has passed its farthest position from shaft 11 and has already moved closer to it, due to the effect of the medium in working chamber 2, because the port in valve plate 12, i.e. inlet valve 8, is open to channel 41, allowing the feed of the pressurized medium to continue.
  • the hotter medium in channel 17 such as the combustion gases from the heater of the medium in working chambers 2 and 3, heats cylinder 1 and lever piston 7 pushes rotary piston 5 (upwards in the figure) clockwise. Simultaneously, the hot medium in channel 17 already starts to reheat the medium that has cooled due to the increased volume of working chamber 2, increasing its pressure.
  • the medium in them simultaneously cools, in turn cooling the medium, i.e. combustion gases, in channel 17.
  • rotary piston 5 pushes the previous work stroke's medium in exhaust chamber 4 through outlet channel 9 (outside the section line) into a space with an essentially lower pressure.
  • Rotary piston 25 continues to push the previous work stroke's medium in exhaust chamber 24 through outlet channel 29 (exhaust chamber 24 and outlet channel 29 are outside the section line) into a space with an essentially lower pressure.
  • the medium can continue to be fed into working chamber 22 through inlet valve 28, until the final stage of its current ( Figure 5) work stroke.
  • the heating effect of the combustion gases of channel 17 has diminished inside cylinder 21, as rotary piston 25 has passed outlet port 19.
  • the engine units can differ from those in Figure 9 by having different sizes with the second engine unit, for example, being longer parallel to shaft 11, to meet different needs, though the various components' diameters remain the same.
  • the engine units can also differ from Figure 9, for instance, by being connected in series, with the requisite number of openings being made in valve plate 12 and channels being made to lead the medium to the right place, with the right timing.
  • the medium is then led to channel 41, through valve plate 12 and channel 8, first to cylinder 1 and, after passing through all the stages ( Figures1 - 8), it moves through outlet channel 9, through valve plate 12 and channel 28, to cylinder 21, where, after passing through all the stages ( Figures 1 - 8), it cools and moves, through outlet channel 29, to a space with a lower pressure.
  • Figures 10 - 17 show, as examples, diagrams of a unit, formed by a series of three machines/engines according to the invention, at 45-degree intervals in a complete 360-degree revolution.
  • the explanations include a reference number in brackets, referring to the current stage of Figures 1 - 8 of each engine unit, Figures 1 - 8 describing the operation of the engine in greater detail, through its various stages.

These heads 71 - 74 can also be used to direct the medium to the requisite place at each time, but, for clarity, Figures 10 -17 use the same inlet and outlet channels as in the previous figures.
  • Figures 10-17 show rotary pistons 5, 25, and 55 of the three units connected in series, as an engine according to the invention, on shaft 11 at different angles to each other, though rotary pistons 5, 25, and 55 can also be in the same position in relation to each other on shaft 11, when the engine blocks will correspondingly be at different angles to each other.

  • the heater possibly used in an engine solution according to the invention is quite small, because the effective surface area of the pistons of the engine is large in relation to the volume of the cylinder and the work stroke continues at a high torque for more than half of every revolution of shaft 11. This means that the amount of medium required is small in relation to the engine's power, so that the engine is powerful for its size and can be applied to a wide range of purposes.

  • the engine's efficiency reduces the total energy consumption for each application, thus reducing the pollution load.
  • An engine according to the invention particularly allows the exploitation of the cleanest, renewable energy sources.
  • An apparatus permits the exploitation of high-temperature energy sources, allowing the exploitation of the energy of exhaust gases and cooling that would otherwise be wasted.
  • An engine according to the invention requires no external cooling, but acts as its own cooler/condenser.
  • the solution according to the invention can even be used to reduce the pollution from the exhaust gases of another engine or device.
  • An engine solution according to the invention can also be connected in series, the medium/gases from the previous engine unit, circulating in channel 17 or released through outlet channels 9, being exploited as the medium/intake gases in the next engine unit, thus extracting the energy content very fully.
  • Particular applications include the exploitation of the exhaust gases or other heat from a combustion engine, through channels 17 and the use of two or more entirely separated and closed heating/cooling/condensing circuits, utilizing a lever-mechanism engine unit according to the invention, or a combined larger totality.
